For Pharaoh will say of the Israelites, ‘They are wandering the land in confusion; the wilderness has boxed them in.’
We have here, I. Instructions given to Moses concerning Israel's motions and encampments, which were so very surprising that if Moses had not express orders about them before they would scarcely have been persuaded to follow the pillar of cloud and fire. That therefore there might be no scruple nor dissatisfaction about it, Moses is told before, 1. Whither they must go, Exo 14:1, Exo 14:2.
Commenting on Exodus 14:1-9
the wilderness hath shut them in--Pharaoh, who would eagerly watch their movements, was now satisfied that they were meditating flight, and he naturally thought from the error into which they appeared to have fallen by entering that defile, he could intercept them.
3. For Pharaoh will say. God here explains to Hoses His design; although, in His engagements with Pharaoh, he had so often gained glorious victories, that the last act still remained to overwhelm him and his army in the sea. He says that Pharaoh, then, will be caught in riffs snare, so as to rush upon his destruction.
